IMPROVEMENT IN MACHINES FOR SETTING UP BARRELS.,

The Schedule referred to 1n these Letters Patent and making part of the same I, AMos Curran, of Boston, in thecounty of Sui'-v folk, in the State of Massachusetts, have invented A certain Improvements in Machines forSetting Staves in Barrels, of which the following is a specification.

The object of this invention is to supply a machine in and by which the staves are .placed and held around the barrel-head, and in position to be trussed and hooped; and j It consists in rthe construction and arrangement of the parts that produce the result sought for.

In the drawingv Y (lignre l is a perspective view of the machine, an

Figure 2 is a view 4in section of some ofthe details.

A represents an adjustable platform or table, which can be adjusted to any desired height by the adjusting-screws a working in nuts a.

y These screws a act to raise the table A from the floor upon which the machine stands.

'B is an adjustable circular table, less in diameter than the bead of a barrel, and is attached to and can be'revolved with and adjusted to any desired height from the table A, by means of the long screw-rod b, which goes from the underside of table B through platform A at its center, and is supported by means ot any snliieient number of legs G C G, attached iirmly to the upper side of platform A by the feet a: x, as seen in iig. 1, or by any other convenient means, andhaving screw-nut c connect them together at their upper ends, (or cast therewith 'as may be,) so that screw-rod b will pass through screw-nut c, down between legs C C G, and through a hole in the center of platform A..

The screw-rod l), when the table B is adjusted at the right height from platfrom A, is held iu its position by set-screws c.

D D D are inclined, bent, and slotted supports that receive the pivoted and slotted levers E E E inthe slots d' above bent shoulders d, the slots c sliding on clamp-screw d". y

Slotted levers E freely slide in slotd of supports D, and, when adjusted to the proper position, are held in such position by clamp-screws d", at the upper ends of supports D.

F F F arecircular clamp-jaws, and of the form seen in fig. 1, and embracing three-fourths, more or less, of the periphery of table B, and are hinged or pivoted tp thf'e upper end of slotted levers E, at f ,.by lng f in s ot Clamp-jaws F, at points where they meet, are halved in such way that the upper part of one is eut away on its top, and its fellow is cutaway on itsbottom half, so that, when they are brought together, the joint is not in a single point, and as seen in g. 1, at o.

In the centerone ofthe three clam p-jaws Fis a pointed spur or pin, f which, when a stave is placed between the clamp-jaw F and edge of table B, and the clamp acting upon it, will hold the stave in place, and allow other staves to be placed on each side of the first one, and between the clamp F and table B.

G in tig. 2 represents a section of the head of a barreland resting upon table B.

H is the stave, held in position, and the crozing pressed by clamp F upon the head G. p

The distance from the platform A to the top of table B is varied to suit the length of the staves to be set up into the barrel, which is done by turning the table and screw-rod b around in nut c, when the table will be raised or lowered, as desired, and held in thcposition by set-screw c.

If short stavcs are to be set up, the table will have to be turned and screwed down to the proper height above platform A, but -in .doing so the screw-rod b may strike the floor, which is prevented by turning screws a, which bear upon the floor, so as to raise the platform high 'enough to give the proper space be tween it and the ioor for the screw-rod b to be turned down and not touch the door.

The clamp-jaws or stave-holders are adj usted to be at the proper height for holding the stares upon the head, and allowing a. hoop to be placed upon the end of the barrel, by means of releasing holding-screw d", and sliding the slotted lever up or down as far as necessary to bring the clamps to the right height when the set-screw d" is turned hard up, and clamp the lever in slot d of support D, thus holding,` the clamps at the right height for forcing the crozing of staves upon the barrel-head.

Operation.

ness of a stave; place-the head G cent-rally upon the table B.; place the iirst stave, one end resting on the platform, so that the center ofits width will come at pinf; then throw the lower end of clamp-lever F out toward the support D, which will hold the stave firmly in its place upon the head 5 both hands of the operator are now free, and he grasps a stave in each hand, and places them on either side of the one first clamped, by sliding them sidewise 'between the table and clamp, continuing this until the first clamp-jaw is full, when the other two clamp-jaws are brought up to their position, when the staves are placed between them and the table to the open space between the clamp-jaws, when the two or three remaining stares are held by one hand of the operator, while he uses the other to place the truss-hoop around the end of v.vel-SE, constructed and arranged to operate in the manner shown anddesoribed.

2. The table B, when constructed to, be adjusted with relation to platform A, in the mannervand for the purpose shown. Y I

3. 'lhe combination of the clamp-jaws F, arranged to operate as described, with the adjustable table B,

for the purpose shown.
